I have my DNS on my android phone set to dns.adguard.com, which has the benefit of blocking ads in even "free" apps/games that are littered with them. This works even on mobile data, so it's better than even a pihole. I wanted to do the same to my boyfriend's iPhone after seeing him sit through probably a dozen ads in one sitting with all the free games he has downloaded, but I found out that Apple literally does not allow you to change your DNS for mobile networks, and you have to manually change it for each wifi network. Weird for a company that claims to prioritize "privacy".
